Lumistar Luminaire USL 05 LED, aluminium

Luminaires (Non-Ex)

Product Picture: Lumistar Luminaire USL 05 LED, aluminium

This sight glass luminaire is designed for universal applications and is ideal either in combined sight and light ports (single-flange version) or for separate ports (two-flange version).

For illuminating the interiors of vessels, tanks, agitators, silos and other, generally closed, containers and reactors and also in visual flow indicators in non-explosive environments.

Suitable for use in the food processing industry.

Compact design, powerful light output: Glare-free illumination; fits circular sight glass fittings to DIN 28120/DIN 28121 or similar, screw-type sight glass fittings in compliance with DIN 11851, as well as visual flow indicator fittings.

Generous light exit and optimised screwed lens aperture

 

Protection class: dust-tight and water jet-proof,
IP 65 in compliance with EN 60 529 / DIN VDE 0470, part 1

Operating conditions: Independent of vacuum/pressure in the vessel. Under no circumstances should a sight glass luminaire be used as a substitute for  the cover flange or instead of the complete sight glass flange assembly or on its own to close a vessel port.

Maximum admissible ambient temperature: 50°C

Straightforward installation using special attachment, ensuring convenience of use: The luminaire is fixed to the cover flange by a hinged bracket in the case of circular sight glass fittings and visual flow indicators.

With screw-type sight glass fittings, the luminaire is fastened to the slotted nut.

Lumistar luminaire USL 05 LED fits the following nominal sizes:
a) Circular sight glass fitting acc. to DIN 28120: from DN 25
b) Circular sight glass fitting acc. to DIN 28121: from DN 40
c) Visual flow indicator: from DN 25
d) Screw-type sight glass fitting in compliance with DIN 11851:
– DN 65, DN 80 are mounted using a separate flange adapter
– DN 80 and larger are mounted using a hinged bracket
• Voltage type: AC/DC
• Operating voltage:
24 V AC/DC 7.5 W LED
230 V AC 5 W LED
